Abstract
The development of the space elevator attracts attention as a study of the precedence of the space development recently. We examine the elevator of the simulation to go up and down at several hundred meters above the ground as these technical fundamental researches now. We measure the posture of own in real time to operate an elevator for high speed / stability, and control of the posture becomes important. Therefore we introduced an attitude measurement system using accelerometers and gyroscopes. Then, we examined a method of the optimization for moving speed as the first step to perfect posture.
